UB04 Boxes 18-28 - What is a condition code and how do I enter them on an institutional claim?

Condition codes are a 2-digit numerical or alphanumeric representation of aspects of a patient, services provided, the type of service venue, and/or billing situations that can impact the processing of an institutional claim by a payer.

These codes are listed in boxes 18-28 on the UB04(HCFA 1450) institutional form.


DrChrono has made it easy to enter these codes on your claim. They are all listed in a drop-down menu for you to select.


  1. Navigate to Billing > Live Claims Feed > Inside patient's encounter > right side of the screen > Cond & Occ tab
